What happened with the Sequence Reruns? I was getting a lot out of them. Were they halted due to lack of a party willing to continue posting them, or was a decision made to end them?

I'm pretty sure they halted because they had gone through the Sequences. Final Words, the last rerun post, was published after Go Forth and Create The Art!, which is listed as the last of the Craft and Community sequence, which was the last of the Major Sequences.
